The middle roll of cold rolling mill is the key component of the rolling mill. The work roll of cold rolling mill is generally divided into two kinds of arc roll friendship roll. If it is used for work roll, it is more suitable for arc roll. For lower work rolls, flat rolls are more suitable. So, generally speaking, people choose according to this criterion.
Plate shape control of cold rolling mill, from its special tools, is more widely used at present, the middle roller level movement and roll seam skew. In addition, if there is a bending roll system in the cold rolling mill, the bending roll system software can be adjusted to maintain the appearance of the operation. The common product quality problems of aluminum strip cold rolling mill include wavy pattern, pattern, vertical bright relative path, roller bearing and embossing. Therefore, people should reasonably solve this practical problem, and take effective measures to avoid the recurrence of this problem.
Four-roll reversible cold rolling machine in the whole process of cold rolling, its support force ratio is generally 1:1, that is, the support force is consistent, but can be adjusted moderately, how to adjust, and how much, is to see the application of machinery and equipment and product quality, this is all by their decision. In a four-high reversible cold rolling mill, the ratio is obtained by measuring the support force precisely with the support force, thus it is measured according to the specific value and is not related to the preset value. In addition, it can be felt to be the working pressure caused on the supporting force test roller, so the use value enterprise is ox. The key difference between the four-roller reversible cold rolling mill and the four-roller cold rolling mill depends on the cold rolling of the four-roller reversible cold rolling mill can be carried out repeatedly, there is no fixed fixed orientation, the general four-roller cold rolling mill only one orientation cold rolling. As a result, the two types of cold rolling mill structure and heat resistance between each other is not the same.
Four-roll reversible cold rolling mill is one of the four-roll cold rolling mills from the perspective of technical specialty. The four-roll cold rolling mill belongs to the technical industry of cold rolling mill, so the four-roll reversible cold rolling mill also belongs to the technical industry of cold rolling mill. Like the general four-high cold rolling mill, it has four rolls, two support rolls and two work rolls.
